Abstract

The objective of this experiment is to observe the elastic and inelastic behaviors of high-rise reinforced concrete frames having non-seismic details. To do this, a building frame designed according to Korean seismic code and detailed in the Korean conventional practice was selected. A 1:12 scale plane frame model was manufactured according to similitude law. A reversed lateral load test and a monotonic pushover test were performed under the displacement control. To simulate the earthquake effects, the lateral force distribution was maintained to be an inverse triangle by using a whiffle tree. From the tests, base shears, crack pattern, local rotations in the ends of critical members and the relations between interstory drift versus story shear are obtained. Based on test results, conclusions are drawn on the implications of the elastic and inelastic behaviors of a high-rise reinforced concrete frame having non-seismic details.

본 연구의 목적은 비내진 상세를 가진 고층 R.C골조의 탄성 및 비탄성 거동을 실험적으로 살펴보는 것이다. 따라서, 국내의 내진 설계규준에 따라 설계 및 시공된 건축물이 선정되었으며, 상사법칙에 따라 1:12의 축소율의 평면 골조모델이 제작되었다. 실험방법은 옥상층의 변위제어에 의해 반전횡하중 실험과 일방향 가력 실험을 수행하였다. 지진효과를 나타내기 위하여, 횡력은 휘플트리를 이용하여 각층에 역삼각형 형태로 분포되었다. 실험으로부터 밑면전단력, 균열양상, 주요부재 단부에서의 국부 회전각 및 층간변위와 층전단력과의 관계를 얻을 수 있었다. 실험결과로부터 비내진 상세를 가진 고층 철근콘크리트 골조의 탄성 및 비탄성 거동에 대해 살펴보았다.
